Custom antibody development

We offer world-leading antibody development platforms based on a proprietary RabMAb® rabbit monoclonal platform, a phage display platform (AxioMx), and a next-generation sequencing platform (NGS-RabMAb®)

Overview

ab6672 detects a band at 25 kDa in Human lung tissue lysate and Mouse spleen tissue lysate, however the signal in mouse tissue is significantly lower. It also binds strongly to a protein at ~55 kDa in Human lung tissue extracts, which we believe represents a glycosylated form of IL6. ab6672 also detects several bands in Human lung tissue lysate within the region of 30-40 kDa. These may represent heteromers of IL6.
Please be aware that this product has low homology with the mouse and rat sequence of IL6 (Rat, 40%; Mouse 41%, UniProt blast) and we therefore cannot guarantee reactivity in these species.

Target

Function

Cytokine with a wide variety of biological functions. It is a potent inducer of the acute phase response. Plays an essential role in the final differentiation of B-cells into Ig-secreting cells Involved in lymphocyte and monocyte differentiation. It induces myeloma and plasmacytoma growth and induces nerve cells differentiation Acts on B-cells, T-cells, hepatocytes, hematopoeitic progenitor cells and cells of the CNS. Also acts as a myokine. It is discharged into the bloodstream after muscle contraction and acts to increase the breakdown of fats and to improve insulin resistance.

Involvement in disease

Genetic variations in IL6 are associated with susceptibility to rheumatoid arthritis systemic juvenile (RASJ) [MIM:604302]. An inflammatory articular disorder with systemic-onset beginning before the age of 16. It represents a subgroup of juvenile arthritis associated with severe extraarticular features and occasionally fatal complications. During active phases of the disorder, patients display a typical daily spiking fever, an evanescent macular rash, lymphadenopathy, hepatosplenomegaly, serositis, myalgia and arthritis.Note=A IL6 promoter polymorphism is associated with a lifetime risk of development of Kaposi sarcoma in HIV-infected men.

Additional bands at : 25 kDa,55 kDa (possible glycosylated form). We are unsure as to the identity of these extra bands.

Tissue lysates were denatured for 10-15 minutes at 90ºC. ab6672 was incubated overnight at 4ºC and the secondary antibody for 1 hour at RT.

IHC image of IL6 staining in human lung formalin fixed paraffin embedded tissue section*, performed on a Leica Bond™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab6672, 1/400, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

For ab6672, it is supplied as a whole antiserum, this means that it is not a purified antibody. The concentration range of 80-85mg/ml, represents the total protein concentration, the actual concentration of the IL6 a...
